- the operation of the air purifier ID is as follows.
- negative pressure is generated behind the filter unit 20.
- an air flow is formed which is sucked from the suction ports 94L and 94R, passes through the filter unit 20, and is blown out from the outlet 34.
- the airflow that has entered the taxiways 92L and 92R from the suction ports 94L and 94R is drawn into the filter unit 20 little by little while moving straight along the filter unit 20 in a straight line.
- the airflow is sucked into the filter turret 20 and changes its direction at right angles, but the coarse dust P contained in the airflow goes straight due to inertia.
- the airflow that reaches the back of the taxiways 92L and 92R passes through the sudden turning sections 95L and 95R and enters the coarse dust accumulation sections 93L and 93R. At this time, due to the sudden turning of the airflow, the coarse dust P is released from the airflow. The separated coarse dust P falls by gravity and is received by the dust box 98. Thereby, the coarse dust P in the airflow can be collected in the dust box 98 without being adsorbed by the filter unit 20.
- the air vents 96L and 96R are arranged on the side close to the air inlets 94L and 94R, the air in the coarse dust accumulating sections 93L and 93R is sucked out to the inlets of the guide paths 92L and 92R. Therefore, even if dust is contained in the air sucked out, the dust is collected by the filter unit 20, or the airflow force is also released when passing through the sudden turning sections 95L and 95R again. Dust can be collected thoroughly.
- the two air guide plates 90L and 90R are arranged symmetrically in the left-right direction, and the left and right suddenly turning portions 95L and 95R are partitioned by the boundary plate 91 protruding between them. Even if the airflow is sucked in from either the left or right side, it is guided toward the center from the end of the filter unit 20, that is, toward the part where the suction force of the blower 30 is relatively weak and the part force is also strong. A stable airflow that reaches the back of the taxiways 92L and 92R is formed. It is.
- the coarse dust accumulating portions 93L and 93R are provided in two stages in the vertical direction, the falling distance of the coarse dust P per coarse dust accumulating portion is reduced, and the coarse dust is reduced. P quickly falls into the dust box 98. For this reason, it is possible to reduce the proportion of coarse dust P that is carried back into the airflow without being able to fall.
- odors and components in the air are adsorbed by the deodorizing filter 21 and fine dust is collected by the dust collecting filter 22.
- the air purified by the filter unit 20 is blown out from the outlet 34.
- the number of dust boxes 98 is smaller than the number of coarse dust accumulating sections, thereby reducing the labor of discarding coarse dust.
- the present invention is widely applicable to air cleaners, air conditioners, electric ceramic fan heaters, petroleum fan heaters, and the like that purify indoor air.
